Thanks for the tips. It doesnt look that bad to me but im a novice when it comes to this. there is still some unrusted part shining through. the outside of the block is pretty bad but the cam and crank journals look pretty good to me some surface rust and a little slight pitting. what is LPS 3 ? im in the military and we use all kinds of lubricants and chemicals but ive never needed to keep rust from forming all together. thanks for the help Pat. its always nice to get advice from an experienced hot roder im pretty new to it myself.
